Found near levittown with bh 1100. $50 gold peice.
Pretty cool find.

No $50 coins were produced circulation in 1877 by the US Mint.
The coins were never officially minted. The House of Representatives approved Guthrie’s proposal for high-value gold coins, but it didn’t pass the Senate, and the proposal for the Union and Half-Union died. In 1877, most likely as a test die for a similar coin, US Mint engraver William Barber produced two variants on the $50 gold coin, two different sizes of the Liberty head on the obverse, and dated 1877. There is no record when they were produce, however, it likely wasn't 1877. Whether there was renewed interest in the California-proposed coins, or a new project, coin collectors are unsure of the source behind those $50 dies.
The two pattern/trial coins produced are house at the Smithsonian since 1885 and are illegal in private hands.
Copies have been sold on TV and internet for years.
